• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sach - thanh trung lieu trong cong van ((juan cao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - thanh trung lieu trong cong van ((juan cao) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sach - thanh trung lieu trong cong van ((juan cao) OR (toan cao))*.
